Oxycodone Controlled-release (CR) oxycodone is an opioid agonist and a schedule II controlled substance with an abuse liability similar to morphine.

Loperamide, 4 mg initially, then 2 mg after each loose stool, not to exceed 8 mg daily Imodium A-D, various generic Loperamide, a synthetic opioid, acts on intestinal smooth muscle to decrease motility allowing for absorption of water and electrolytes. Poorly penetrates the CNS and has a lower risk of side effects compared with diphenoxylate or opiates. Not considered a controlled substance. 

The primary aim of the CSA and the DEA s implementation of the law is to find those physicians who are prescribing opioids and other controlled substances for nonmedical purposes. All of the entities included in the chain of the production and distribution of the controlled substance are carefully watched by the DEA for signs of irregularities. Violators of the CSA can be charged with a felony and are subject to fines and imprisonment.

Diphenoxylate HCI (2.5 mg) and atropine (0.025 mg) are combined in tablets or 5 mL liquid and are used effectively as symptomatic treatment for diarrhea. The typical dose is two tablets or 10 mL every 3 to 4 hours. The combination with atropine enhances the block of acetylcholine-stimulated peristalsis, and the adverse effects of atropine helps to limit the abuse of the opioid. The combination is Schedule V under the Controlled Substances Act. Diphenoxylate itself has low p opioid agonist activity. It is metabolized rapidly by ester hydrolysis to the zwitterionic free carboxylate (difenoxin), which is five times more potent after oral dosing. The zwitterionic properties of difenoxin probably limits its penetration into the CNS and explains the low abuse potential of this agent. High doses of diphenoxylate (40-60 mg) will cause euphoria and addiction. 

Dextromethorphan HBr is the ( + )-isomer of the 3-methoxy form of the synthetic opioid levorphanol. It lacks the analgesic, respiratory depressant, and abuse potential of p opioid agonists but retains the centrally acting antitussive action. Dextromethorphan is not an opioid and is not listed in the Controlled Substances Act. Its effectiveness as an antitussive is less than that of codeine. Dextromethorphan is available in a number of nonprescription cough formulations.

Immunochemical methods have been reported for the determination of these substances in body fluids (see Table 8) in clinical and forensic analyses. In the case of illicit use of opioid drugs, methods have also been reported for the control of drug abuse and assessment of intoxication using body fluids, tissue extracts, post-mortem specimens, and seizure samples. For this reason there are several commercially available immunochemical methods (see Table 4).
